Numbers on my engine

[Eastyorker]

I found these numbers on the passenger side of my engine. What do they tell me?

B*19*70
2536430-5

The first one is pretty straightforward , its the cast date, it may even have a little clock hand symbol which indicates what shift time, what type of motor? LA or B/RB?
